QuestionCalculate $12.4 + (25 \div 5)^{2}$ .

Studdy Solution

STEP 1

Assumptions1. We are given the expression $12.4+(25 \div5)^{}$ . . We need to follow the order of operations, also known as BIDMAS or PEMAS, which stands for Brackets, Indices (or Exponents), Division and Multiplication (from left to right), Addition and Subtraction (from left to right).

STEP 2

First, we perform the operation inside the parentheses. According to BIDMAS, division should be done before squaring.
$12.4+(25 \div5)^{2} =12.4+(5)^{2}$

STEP 3

Next, we perform the squaring operation.
$12.+(5)^{2} =12.+25$

STEP 4

Finally, we perform the addition operation.
$12.4+25 =37.4$ So, $12.4+(25 \div)^{2} =37.4$ .
